WIND OW-ADJUSTER.

Specification of Letters Patent.

Patented Jan. 28, 1919.

Application filed September 9, 1916. Serial No. 119,153.

To all whom it may concern:

Be it known that I, FRANCIS A. WmsLow, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented a certain new and useful Improvement in Window-Adjusters, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention provides an adjuster for windows or the like, particularly for holding windows of the type shown and described in my prior application, Serial No. 810,937 filed January 8th, 1914, in any desired one of a number of positions. The window described in the above patent is balanced as to weight and is balanced for uniform wind pressures, but sudden gusts of wind sometimes act unequally upon the window sections and cause movement of the same.

My present invention aims to provide simple and convenient means for automatically holding the window shut after the same is moved to the closed position and for holding the window against movement in the desired open position.

The particular form in which I have chosen to embody my invention is neat, inconspicuous,simple and convenient.

In the accompanying drawings I have illustrated one embodiment of my invention.

Figure 1 is a top plan view of the adjuster showing the same attached to the sash and the window frame;

Fig. 2 is a front elevation showing the bracket of the adjuster in section;

Fig. 3 is a side elevation with parts broken away; and

Fig. 4 is a diagrammatic elevation of the window with the adjuster attached.

As shown in Fig. 4, the particular type of window to which my invention is preferably applied comprises a window frame 1 for receiving the two sashmembers 2 and 3, which are connected to each other through the arm 4 to which each sash is pivoted. The arm 4 is pivoted at its center to the frame 1 and thus the two sash members 2 and 3 may be moved with a combined rotary and sliding movement, as is understood by those skilled in the art.

The adjuster 5, as is shown in Fig. 4 is connected to the frame and to the lower sash member near the bottom of the window frame 1. The adjuster comprises the stay plate 6 which is secured to the limb 7 of the channel iron which comprises the frame 1.

The stay plate 6 is connected as by means of the screws 8, as shown in Fig. 3, and projects out from the frame 1, having its outer end flared out slightly, as shown at 8 in Fig. 1. The stay plate 6 is also provided with flanges 9 resting against the front of the channel 7 and seating firmly upon the same. The flanges 9 continue around the outer edge of the stay plate 6 except where the same is cut away at 10 (see Fig. 3) to form an engaging notch or socket for the latch member 11 which is pivoted to the bracket 12. The bracket 12 is bolted to the flat outer face of the channel 13 which comprises the frame of the sash member 3 and this bracket projects in a line'generally parallel to the stay plate 6. The outer end of the bracket is slotted to receive the latch member 11 and a pin 14 forms the pivots between these two members. The latch member 11 comprises the tongue 15 which'fits in the slotted end of the bracket 12 and forms the pivots for this latch member. The member 12 further comprises the tongue 16 which is adapted to drop into the notch 10 by the weight of the latch member when the window is closed and a thumb piece 17 which is adapted to be engaged by the hand of the operator to lift the latch member preparatory to opening the window. The bracket 12 is gained or notched at 18 to render the thumb piece 17 accessible. The bracket 12 carries at its lower end an enlargement 19 which is adapted to receive a bolt 20 which is slidable in and out, as indif cated by dotted and full lines in Fig. 2. The bolt 20 is adapted to engage the slots 21, 22, and 23 in order to hold the window in the desired open position. Movement of the bolt 20 is limited by a pin or screw engages a slot 25 cut in the back or base of the bracket member 12.

- The latch member 11 is freely pivoted about the pin 14 and drops of its own weight into the notch 10. The stop 26 on the bottom of the tongue 15 of the latch member 11 prezents excessive movement of the latch mem- Downward motion of the latch memberll 24 which diflerent points to hold the window in one of when released from open holding relation to several open positions and to lock the sashes automatically lock the sashes against open- 10 against opening. ing when the sashes are moved to closed po- 9.
